What is your educational background?

I have a degree in Surveying Engineering (which is now called Geomatics Engineering) from Greece (Athens) and higher degrees (MScE and PhD) in Geodesy and Geodynamics from University of New Brunswick in Fredericton.

What is your most memorable project?

I greatly enjoy all projects I work on, so it is difficult to choose… One of the most memorable ones is when I undertook the task to determine the post-glacial rebound signature using legacy gravity measurements, which were taken over 50 to 60 years period.

 If you could create any course at York, which course would you create?

I would create an open course, which would bring together science, engineering, arts, humanities, and social sciences,  to demonstrate that there are no boundaries among these disciplines.

Which part of teaching is most exciting to you?

It is definitely interactive teaching and “flipped classroom” concept, where the students take over the learning process. I simply don’t like monologues.

Can you tell us about blended learning?

Blended learning takes a step away from simple traditional teaching from the podium, which I consider a one-way communication. Learning has to be experienced through a variety of activities, such as projects, lectures, interactive and experiential learning, etc. These are all different learning modes, taken from our daily experiences – when we listen to seminars, interact with people, work on projects… basically, the way life teaches us on a daily basis.

What do you like/dislike about York the most?

Like:  The students and the diversity of cultures.

Dislike: Micromanagement and bureaucracy.

Favorite building at York?

Bergeron, because it is relatively open to interactive learning.

What’s your pet peeve?

Get off your cellphone and texting, be social and interact face-to-face! Turn it off  when in class, at a social gathering, at a restaurant, in meetings…

Favorite quote?

“Great spirits have always encountered violent opposition from mediocre minds.” By Albert Einstein

Favorite Lassonde colour?

Blue, the colour of our department.

Favorite food? 

I love food in general!

Favorite movie?

I don’t watch many movies, but I prefer light ones, such as “Mama Mia”.

What do you do in your free time?

I normally work on cars or work at home building things.

If you could be any age, which age would you choose and why?

I would choose thirties, because this would give me enough time to do all the things I want to do.

Where would you like to travel to?

I’d like to go to exotic islands in the Atlantic, Pacific, Caribbean, etc.

Interesting fact about yourself?

I don’t need much sleep, I don’t get tired, and I can go for a long time without food.

ESSE Teaching Retreat

On Wednesday, February 22nd, a number of ESSE faculty members as well as staff and one grad student attended ESSE’s annual teaching retreat. It was again held in the Victoria room at Black Creek Pioneer Village. As they arrived in the morning, faculty members were encouraged to sit with other faculty members in their programs: Geomatics, Space, and Earth and Atmospheric Science in order to be prepared for a group activity. Franz led the morning session talking about active learning exercises and their implementation to increase student understanding and grasp of material, as opposed to traditional lecture-type learning. The bulk of the morning was spent reviewing our program themes and the learning outcomes, with some suggestions identified for better alignment of learning outcomes. Some conversations also made use of the student focus group feedback gathered for some of the programs just before reading week. The morning concluded on rubric-based assessment in engineering disciplines, and Franz had a chance to show everyone some of the results of our accreditation data collection from the Fall semester. We have noticed that this semester, there is a big improvement in the number of courses with posted CLOs, however there is still room for more of us to provide assessment grades broken down by learning outcome! (On which note – a gentle reminder to provide the necessary accreditation materials this semester!). Regina drove an ESSE-related quiz asking us how well we knew our students and courses; the winners of this year’s quiz were Mojgan and Costas. In the afternoon, programs reviewed courses that were common with other programs in the department, and towards the end of the day, undergraduate program directors stayed at their tables and other faculty members switched tables to review other programs’ structures and changes. The discussions during the day were honest and open, and it was great to have so many faculty members together to discuss teaching in the department. A feedback survey will be available soon.

By: Dr. Franz Newland and Sandra Sinayuk

Student Open Feedback Forum

A series of Student Open Feedback Forums has been held for undergraduate programs in ESSE Department: Geomatics Engineering on February 15th, Space Engineering on February 16th, and Earth and Atmospheric Science on February 27th. Students met with the Chair of the department, Dr. Regina Lee, as well as with other faculty members and staff from the Student Welcome and Support Centre and the Dean’s Office. Students provided their opinions and suggestions about specific courses, the program in general, and teaching methods and style. They also learned about the changes made to the programs since the last Forum.


An Interview: Dr. John Moores

What is your educational background?

I did my undergrad in Engineering Science at University of Toronto, and then a PhD in Planetary Science at University of Arizona.

What is your most memorable project?

My most memorable project is the Huygens Probe, since it was the first space mission that I had worked on. It is the first spacecraft that has ever descended on Titan, so it was an exciting mission to begin with. I was developing radiative transfer simulations of Titanian atmosphere and matching them up with images taken by the spacecraft. We were looking for clouds, changes in aerosols, etc.

We worked in a big team with European Space Agency, and I got to be one of the first dozen people to see the surface of Titan. It was fun!

It was interesting to see how Mother Nature likes to surprise us: how imperfect data can be. I find the same with other missions as well—against all the theories, data is never as good or as bad as you expect.

If you could create any course at York, which course would you create?

A course on geophysics of planetary surfaces.

Which part of teaching is the most exciting to you?

It is always rewarding to see students getting interested in the subject, to see their grades improve and how they succeed at the end, even if they started out shaky.

What do you like about York the most?

It’s a pretty campus – especially in the summer, when it is nice and quiet.

Favorite building at York?

Scott Library, because it has a big and spacious atrium.

Favorite color?


Favorite food?

Chocolate. My wife is a project manager at Cadbury, so I have no choice!

Favorite movie?


What do you do in your free time?

I run; I also like racket sports, such as badminton, squash, and tennis.

Where would you like to travel to?

Asutralia – it is a big open country by the ocean. I grew up by the coast, and kind of miss that.

Interesting fact about yourself?

I used to work for RCMP.

Dr. John Moores’s Research Identifies Icy Ridges on Pluto

Using a model similar to what meteorologists use to forecast weather on Earth and a computer simulation of the physics of evaporating ices, a new study, published in the journal Nature, by York University’s Professor John Moores, Department of Earth and Space Science and Engineering at York’s Lassonde School of Engineering, has found evidence that snow and ice features previously only seen on Earth, have been spotted on Pluto.

Penitentes” which are formed by erosion, are bowl-shaped depressions with spires around the edge, and are several metres high.

The groundbreaking research, done in collaboration with researchers at NASA and Johns Hopkins University, indicates that these icy features may exist on other planets where environmental conditions are similar.

The identification of the ridges of Tartarus Dorsa as Penitentes suggests that the presence of an atmosphere is necessary for the formation of penitentes, which would explain why they have not previously been seen on other airless icy satellites or dwarf planets,” says Moores. “But exotic differences in the environment give rise to features with very different scales. This test of our terrestrial models for penitentes suggests that we may find these features elsewhere in the solar system, and in other solar systems, where the conditions are right.

Moores, along with his York postgraduate fellow, Dr. Christina Smith, Dr. Anthony Toigo, at the Applied Physics Laboratory, Johns Hopkins University and NASA Research Astrophysicist, Dr. Scott D. Guzewich, at the Goddard Space Flight Center in Maryland, USA compared their model to ridges on Pluto imaged by the New Horizons spacecraft in 2015. Pluto’s ridges are much larger – 500 metres tall and separated by three to five kilometres – as compared to their meter-sized earthly counterparts.

This gargantuan size is predicted by the same theory that explains the formation of these features on Earth,” says Moores. “In fact, we were able to match the size and separation, the direction of the ridges, as well as their age: three pieces of evidence that support our identification of these ridges as penitentes.”

Moores says though Pluto’s environment is very different from the Earth – it is much colder, the air much thinner, the sun much dimmer and the snow and ice on the surface are made from methane and nitrogen instead of water – the same laws of nature apply. Both NASA and Johns Hopkins University were instrumental in the collaboration that led to this new finding. Both provided background information on Pluto’s atmosphere using a model similar to what meteorologists use to forecast weather on Earth. This was one of the key ingredients in Moores’ own models of the penitentes, without which this discovery would not have been made.

Dr. Gordon Shepherd Receives the COSPAR William Nordberg Medal

In June, the international Committee on Space Research (COSPAR) has announced that Gordon Shepherd had been awarded the COSPAR William Nordberg Medal. It was stated that he would receive the award on August 1st during the 41st COSPAR Scientific Assembly in Istanbul, Turkey. On July 15th, after an attempted coup in Turkey, the COSPAR officials found that they were speaking to different representatives, who offered to have President Erdogan give an invited talk at the Assembly. However, the Assembly was later cancelled by the COSPAR, so Gordon received the medal by mail. The concluding paragraph of his citation follows:

Professor Shepherd is one of the world’s foremost scientists studying the physics of the Earth’s middle and upper atmosphere. He not only understands deeply the workings of the Earth’s middle and upper atmosphere, but he is also a superb innovator of sophisticated instruments that continually push the envelope”.

For the Assembly, Gordon was asked to submit in advance a brief acceptance of the award, which he would have spoken had he been there, which follows:

I am both honoured and humbled to receive this medal. William Nordberg and I were contemporaries; he was born one year before me, and took up his position at NASA two years after I was appointed to the University of Saskatchewan. Alas, we never met. I feel particularly celebrated at receiving a COSPAR medal, as COSPAR is the international organization with which I have been most deeply involved. I attended my first Scientific Assembly in Prague, in 1969. I remember well the one in Canada in 1982, and again in 2008, when I chaired the Executive Committee for the Assembly, while serving eight years

as a Bureau member. I am totally indebted to those many colleagues and family members who supported me in the marvellous activities over the years that led to this award”.

The latest issue of the Space Research Today magazine from December 2016 included an article about Dr. Shepherd’s achievement:

Professor Gordon Shepherd has made many distinguished contributions to our understanding of the upper atmosphere through the development of clever instruments and scientific insights revolutionizing our view of its dynamics and chemistry. Professor Shepherd is a pioneering scientist who has continuously developed instrumentation to measure key features of the upper atmosphere.”

Here is a brief biography of William Nordberg:

“William Nordberg moved from Austria to the USA in 1953, and was appointed in 1959 to the Goddard Space Flight Center within the recently created NASA. Under his leadership in 1960, the first weather satellite series, called TIROS, were launched, the first to give information about cloud formation and hurricanes. These were followed by three other satellite programs: ITOS, Nimbus  and Landsat. In 1975, he was awarded the William T. Pecora Award and the highest NASA award, the Distinguished Service Medal. In 1974, he was made director of Space Applications at NASA. Today Nordberg is considered the “father” of the weather and remote sensing satellites.  NASA presents the annual William Nordberg Memorial Award for Earth Science, and COSPAR awards the biennial William Nordberg Medal. William Nordberg died of skin cancer in 1976”.

An Interview: Prof. Franz Newland

What is your educational background?

I went to school in California until senior kindergarten, as well as spent 6 months going to school in Bahamas. However, most of my education I obtained in the UK. I have received a degree in Aerospace Systems Engineering in South Hampton, then a PhD in Tracking Clouds and Satellite Images using Artificial Intelligence. I did my PostDoc in Toulouse in Orbit Determination of Space Debris near the Geostationary Belt Using Ground Based telescope.

Please tell us about your first few years at York.

The first 1.5 years have been exciting, as the students are very enthusiastic here. I would also call it refreshing—York is a nice place to question long held assumptions. In the industry, you often have to stick to the traditional path and old ways of doing things. However, in academia, I have an opportunity to help the next generation to follow the new path, as well as challenge the stereotypes that I wasn’t able to challenge in the industry.

What is your most memorable project?

On of them is being able to work on the Automatic Transfer Vehicle (ATV) European Resupply Vessel for the International Space Station (ISS). It is a bus-sized spacecraft carrying the equipment for the use of ISS, which flies to the station and autonomously does rendez-vous and docking to it. It is a truly international project, involving Europeans, Americans, and Russians.

Another memorable project is my first CubeSat in Canada. It’s fascinating how in just 7.5 months you can go from a blank sheet of paper to a fully functional satellite.

Lastly, I really enjoyed the Capstone course. It is a lot of fun seeing the variety of engineering problems that the students are tackling. If a couple of them succeed, they will actually solve some problems I’ve been running into for awhile.

What do you like/dislike about York the most?

Like: The diversity—York is not as diverse as it could be, but definitely more diverse than most of the other institutions. However, it is still lacking the gender diversity in Engineering. In Toulouse, there was a much higher percentage of women in one of  the Operations Centers, but  long strives in providing a welcoming environment. Lassonde, on opposite, produces a comfortable and open environment, even though we still need to work on breaking the hidden barriers.

Dislike: Not having enough time – I would love to find more time to be able to do more for students.

Favorite building at York? I like the new Bergeron building. I studied clouds in my PhD and spent hours looking at sequences of cloud images, so I find Bergeron’s cloud metaphor lovely. In addition, I do like Petrie, because it’s my home.

What’s your pet peeve? Spelling and grammar.

Favorite quote? The probability of success is difficult to estimate, but if we never search, the chance of success is zero.” by Philip Morrison and Guiseppe Cocconi

Favorite color?  Blue, because it reminds me of clouds.

Favorite food?  Cassoulet – it’s hot bean and duck stew popular in Southern France. It warms you up during the winter!

Favorite movie? “Charlie and the Chocolate Factory”, because Willie Wonka is one of the few literary engineers who  inspire people.

What do you do in your free time? I have a 7 year old at home, so I spend most of my time with him. Otherwise, I play music: I play flute and some piano.

If you could be any age, which age would you choose and why? I would want to be a kid again. I see every day how my son explores the world, and it would be wonderful to see it through those eyes again.

Interesting fact about yourself? I used to have a Californian accent until I was 11.
